Additional STP RAI for Emergency CR Amendment

Drew, As discussed, here is one additional questions to be answered on the docket so that the staff can complete its review of your emergency request for an amendment date December 3, 2015.
7. On page 19 of 22 of your December 3, 2015, emergency amendment request, you state that 10 CFR 50.62(c)(3) concerning an alternate rod injection system as stated in Standard Review Plan, Section 4.6 are for boiling water reactors and do not apply to the South Texas Project Unit 1. The staff agrees that the BWR portion of the Anticipated Transient Without Scram (ATWS) rule, 10 CFR 50.62(c)(3), does not apply; however, the remainder of the ATWS rule, 10 CFR 50.62, should be considered by STP since it does apply to pressurized water reactors. Provide the impact on ATWS for STP considering the removal of control rod D6
Thanks, Lisa Lisa Regner Sr. PM NRR/DORL/LPL4-1 301-415-1906 O8D08 1
